The lid is why this one keeps ending up in our hands. The rotating cover has three positions: one lines the straw opening up for a long pull, one leaves a wide mouth you can drink from without a straw, and one shuts the slot over. It sounds like a gimmick until you notice the cup is empty and you never thought about it — which is the whole job of a 40-ounce tumbler.
The rest of the package is a double-wall cup that holds 40 ounces, a tapered base that settles into most car cup holders, and a handle wide enough for three fingers while the other hand has the keys. At 1.4 pounds empty it is a desk, kitchen, and car cup rather than a hiking one, and that is the trade we are glad to make: the size is what keeps you off the refill treadmill. It also comes in more colors than anything else here, which is not why we recommend it, but it is why the cup does not look like equipment on a counter.
Stanley backs it with a lifetime warranty, and on a cup this heavy that promise earns its keep: the handle takes the full load every time you lift a full tumbler one-handed, which is exactly the kind of stress a warranty is for. It is the one we pull out of the cabinet first, and the one we hand to guests who ask what to buy.
What We Like
- 40 ounces cuts refills to a couple a day
- Tapered base fits most car cup holders
- Three-position lid switches from straw to open sip
- Lifetime warranty backs a heavy-use cup
Worth Noting
- Lid isn't leakproof with the straw in
Our default recommendation: 40 ounces, a lid that switches between straw and open sip, and a base that fits a cup holder — just keep it off its side.
